Storage of wet cotton
1. Seed cotton should be stored in the warehouse and the warehouse should be dry. Lay clean and dry bricks on the ground, leaving a certain gap between bricks and bricks, with a width of not less than 20 cm, to ensure air circulation; bricks covered with bamboo mats or reeds, and then stacked with cotton.
two。 Cotton picked back, do not dry directly on the ground, should be laid on the bamboo bed or set up bamboo curtains to dry, the drying speed is fast, and will not be mixed with three wires. When cotton can make a crisp click when it is exposed to cottonseed teeth, the moisture content of seed cotton is generally about 7.5%, which can meet the humidity requirements of long-term storage.
3. Stiff petals, pre-frost flowers and post-frost flowers should be collected and released according to the quality of cotton. Stiff cotton and post-frost flowers should be different from pre-frost flowers and should be sold separately. Although all kinds of cotton are mixed together, it will sell a few more yuan in terms of surface weight, but it also lowers the price of all the good cotton sold, and the loss outweighs the gain.
4. Try not to use plastic woven bags and other parcels to ship cotton or use it as a binding rope, so as to prevent the mixing of three filaments as much as possible. Bags for picking and shipping cotton, large bags are replaced with white cotton bags, and storage staff should wear cotton hats to prevent hair loss from mixing with cotton.

High quality cultivation techniques of Color Ecological Cotton
Caoxian Special Economic Animal and Plant Research Institute of Shandong Province has achieved high economic benefits by introducing green, brown and other natural ecological cotton. Has been rapidly promoted in the local area. In order to obtain high yield and high quality of colored cotton, the following field management should be done well in the later stage. 1. Watering autumn water, spraying and protecting bolls have significant effects on preventing premature senescence of cotton, reducing shedding of cotton bolls, increasing boll weight, improving seed maturity and fiber quality. The specific method is to adopt small trenches to irrigate the root water and spray the whole plant with cotton boll protector at the same time. two。 Fine pruning, reduction
